ARM: mmp: add more compatible names in gpio driver

Browse source 
Since more driver names are added into platform id, do the same thing on
compatible names for DT mode.

* Marvell PXA GPIO controller
Required properties:
- compatible : Should be "mrvl,pxa-gpio" or "mrvl,mmp-gpio"
- compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
"intel,pxa27x-gpio", "intel,pxa3xx-gpio",
"marvell,pxa93x-gpio", "marvell,mmp-gpio" or
"marvell,mmp2-gpio".
- reg : Address and length of the register set for the device
- interrupts : Should be the port interrupt shared by all gpio pins.
There're three gpio interrupts in arch-pxa, and they're gpio0,
